AUTOIMA'IIC HAND KNITTING MACHINE.

Application filed April-15, 1922, Serial No. 553,052. Renewed December 6, 1923.

Knitting Machines, of which the following is a specification.

p This invention relates to a hand knitting machine, having particular reference to a small hand operated device of this kind,-the

invention having for an object the provision of a simple and inexpensive device of this v kind by use of which the operation ofknittion being intended more particularly for knitting narrow tubular elements which may be used as ornamental braids.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had tothe follow ing description and accompanying drawings, and to the appended claims in which the various novel features of'the invention are more particularly set forth.

As here embodied my improved knitting machine comprises a cylindrical body 10 the axial passage through which is indicated at 11. Formed in one endofv this body are a series of recesses or sockets 12, which'extend parallel to the axis of the body 10 and are spaced evenly therearound. The depth of these sockets is here shown as about one-half of the length of the body 10 and they have is a detail side elevation of the diminished extensions 12" at their inner ends.

in the needles 14; whose outer ends project,

beyond the end of the body 10 and whose inner ends. engage in the diminished extensions 12, the needles being urged outwardly by expansion springs 15 coiled around their inner ends and bearing against collars 16 fixed to the needles, these collars also serving to guide the needles by engaging the walls of the sockets 12. Fixed to the collars are pins 17 which project outwardly through ting maybe greatly facilitated, the inven-' Fig. 4 is a detail perspective view of the 7 movement on the body 10, causing a second slots 18 in the body 10 and have heads. 19

fixed to their outer ends. Y

Rotatably mounted on the body 10 is ring 20 held against axial movement by a series of studs 21 fixed thereto'and engaging F in a circumferential'groove 22 in the body 10. Upon the lower side of this ring 20 are V The needles 14 have hooks 26 on their outer ends, and have pivoted thereto a short distance from'their outer ends the latches 27 whose function is to permit of the loops of yarn sliding freely over the hooks. 7

It is believed that the manner of use of myimproved knitting machine will be readily understood from the above description. The yarn is first passed around the needles under the latches 27when the needles are in their uppermost positions, from'the sleeves and then inserted through the aperture 11, where it may be engaged by a hook 30 on a weight 31 attached by a chain 32 to the "body 10, the yarn being thus held tensioned. The ring 20 is then given a rotary layer of yarn to engage the needles under the hooks 26 but above the latches 27. Immediately after this second layer of yarn engages the needles the latter are depressed by the cams 23 engaging the pins 17, this I movement causing the latches 27 to swing up to closed position by reason of their engagement with the ends of the body 10, thus permitting the first layer of yarn to slip over the needles. -As the ring 20 rotates further, the springs 15 throw the needles forward and the layer engaged in the hooks 26 is moved downward along the needle and under the latch 27 which swings to accommodate this movement. This second layer is again discharged over the needle points after a third layer is caught in the hooks,

the operation being repeated indefinitely, the knitted web passing down through the opening 'and'may be kept under tension by hook ing the weight 31 thereon, this weight being adjusted along the web as required. By feeding a air of different colored strands to the device I may obtain a knitted web 25-through which the thread oryarn'to be i'woven is led from suitable skeins or balls.

comprising two different colors as will be apparent.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:

1. A device of the class described comprising a cylindrical body, a series oi needles spaced aroundthe axis of said body and projecting from one endthereo'f and being located in sockets formed in said body, said needles being parallel to the axis of the said body and movable longitudinally of themselves thereon, hooks and latches on said needle, said latches being adapted to be closed on said hooks on inward movement of said needles in said body, pins on said needles projecting radially outward through slots in said body said slots leading from the said sockets, a ring rotatableon said body, a pair or cam projections on said ring adapted to engage said pins to depress said nee dies; springs coiled around the inner ends of said needles-and urging the same outward. i

2. A device of the class described comprising a cylindrical body, a series of needles spaced around the axis of-said body and projecting fronijone end thereof and being located in sockets formed in said body, said needles being parallel to the axis of the said body and movable longitudinally of themselves thereon, hooks and latches on said needle, saidylatches being adapted to be closed on saidhooks on inward movement of said needles in said body, pins on said needles projecting radially outward through slots in said body said slots leading from the said sockets, a ring rotatable on said body, a pair of cam projections on said ring adapted to engage said pins to depress said needles, springs coiled around the inner ends of said needles and urging the same outward, and means for winding strands of yarn across the outer faces of said needles.

'3. A device of the class described comprising a cylindrical body, a series of needles spaced around the axis or said body and projecting from one end thereof, said needles being parallel to the axis or" the said body and movable longitudinally of themselves thereon, hooks and latches on said needle, said latches being adapted to be closed on said hooks on inward movement of said needles in said body, pins on said needles projecting radially outward through slots in said boc y, a ring rotatable on said body, a pair of cam projections on said ring adapted to engage said pins to depress said needles, springs coiled around the inner ends of said needles and urging the same outward, and means for winding strands of yarn across the outer faces of said needles, said means comprising a pair of sleeves on said ring through Which the yarn is passed, said sleeves being circumterentially spaced with respect to said cams.

In testimony whereof I have affixed my signature.
